AS7C1026B-12TIN

Overview

The AS7C1026B-12TIN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V and features a maximum access time of 12 ns. The device supports a maximum supply current of 100 mA and functions in an industrial temperature range from -40°C to +85°C. It utilizes a parallel interface and is housed in a 44-pin TSOP II surface-mount package.

Feature Summary

• Asynchronous operation with parallel data interface
• Industrial temperature rating for extended environmental stability
• Single 5V power supply compatibility

Applications

• Industrial control systems requiring robust memory performance
• Embedded applications operating in extreme temperatures
• Data storage in 5V logic-based hardware architectures

Procurement Notes

Verify the specific suffix 'TIN' against official manufacturer documentation to confirm the TSOP-II-44 package and industrial temperature grade. Ensure that the 12 ns speed grade matches system timing requirements. Confirm RoHS compliance status through the latest datasheet before integration into regulated assemblies.

Selection Notes

Select this component when a 64 K x 16 organization is required for 5V systems. Compare against the AS7C1026B-20TIN if slower speeds are acceptable, or consider the AS7C1026B-15JINTR for tape-and-reel packaging needs. Validate pinout compatibility with existing PCB layouts designed for 44-pin TSOP packages.

Part Context

This part belongs to the AS7C1026B series of high-speed SRAMs. It shares architectural similarities with other members like the AS7C1026B-20TIN but offers faster access times. The series is designed for general-purpose memory applications where non-volatile retention is not needed but rapid read/write cycles are critical.

Replacement Considerations

The AS7C1026B-20TIN serves as a verified alternative with identical pinouts and specifications, differing only in the 20 ns access time specification.
